| 摘要 | PURPOSE:To improve the corrosion resistance of parts buried in the ground by tearing spheroidal graphite particles from the surface of spheroidal graphite cast iron as a base material and by thermally spraying ceramics on the surface of the cast iron. CONSTITUTION:Structural parts buried in the ground such as a bolt and a nut are made of spheroidal graphite as a base material. Spheroidal graphite particles 4 are torn from the surfaces of the matrixes 2 of the structural parts and ceramics is thermally sprayed on the surfaces of the parts to a prescribed thickness so that holes 6 formed by tearing the particles 4 are filled with the resulting thermally sprayed ceramic layers 8. Thus, structural parts having superior corrosion preventing performance and improved durability can be provided. | ||||||
